Calculate the pH of a solution prepared by dissolving 0.37 mol of formic acid (HCO_2H) and 0.23 mol of sodium formate (NaCO_2H) in water sufficient to yield 1.00 L of solution. The K_a of formic acid is 1.8 x 10^{-4}.

Particle exchange energy though elastic collision , hope this .

The closer the atoms are to becoming ionic the more highly dense the negatively charged side gets.

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
